T0 all whom t may concern: V'Be Iit known'that l, 'JHN F. STANDISH, a citizen fof the` United States, residing at Wiiithrop, in thel county .of Suo'lk and vSta'tepf .Massachuscrtts',I have invented certain' ,Improvements -in QHeelAssembling Machines, of wvlii'ch 'the following' description, iiiconnection vv'ithI the accompanying draw- :inz'g'slfisI a specification, like Areference characterson the dra Uings' indicating like parts in lilGlSVfill gef .l l' I y l I l 'J'AT his inventionrelates to the manufacture @felices and more particularly to" machines 'forfassemblin'g heels.' For villustrative ypurposes theinventionis described asenibedied automatic machine for assembling heel seetioiis or lifts 'and securing Vthe'ii'i together ogforiii coinpleteheels. An' object' o'f theinvention is to provide a machinearranged, 'Without sacrilice of other utility', to asseinble'leatherand rubber heel s'ecti'nsbrI lifts in such a manner vthat the heels`-thus 4assemblerl l'may :u'sed'fi'n the manufacture of shoes according to a method fdisclo'sed'and'claimed in Letters APatent of theUnited States No. 1,288,258, granted Dec'e'rriber "17, l9 l8,`whicliA covers 'a method of h'eieling shoes in which 'leather and rubber heelfs'ection's ,are permanently secured togetherl iiisuperiniposedrelation prior to the attmcliiifieiit olf the ass'eii'ibled heels to the ,further object' of thelinvention isl the p r'ov ionlof a"power-operated,machine airf ranged 'to `assemble and secureftogether.'the

" 5i' fe'ature' of" the invention consists of novel means "for'taking thel heelk sections from ai plnrality of .magazines and superimposing them in assembledV relation.

'notherfeatureof the invention consists offan v"improved presser memberv and 'associa'ted parts for squeezing together the superimposed sections landkfor thereafter transferring them to discharging position.`

Iii'the illustrated machine separate magazines aire'rprovided for the leather and rubber heel sections or lifts. Before these heel sections are lplaced in the magazines7 the upper rfaces of the rubber sections and the lower surfaces of 'theleather sections may be Mftzedvvvi'th cement', which is allowed to dry Without further handling of the heels. Heel sections in this conditionmay'be inserted in the magazines and as lon'gas tivo cement coated surfaces d'o notcome' together they vill feed throughlthe magazines"ivvithout sticking. "From the "niagazines'ithe sections arel transferredtoa support on which they are superimposed `with the cement 'covered upper Asurfaceof a rubber section incontact vv'ith the' cementlcovered Vlower"surface-of"a leather section. presser memberltl'ienoperates to squeeze theheels tolsecurethe sections teg-ether, picks them up,"carrie"s"them oli, and discharo'es them'atafsuitable point.

While thel invention is disclosed as'mem bodied in a specific, auton'iatic machine," it should be remembefred'that thisis primarily for illustrative purposes, and' 'that r the invention in somel of-itsvfeatures in'nolvvay liniited thereto; for ei'raznple," 'the means for squeezing tcgetherthe assembled lifts and thereafter transferring them tothe point of discharge lis in no yWay limited 'in'its utility to machines in the operation of Which t'l'ie superimposing of the lifts isautoniatie or even mechanical. lVith theabove and other objects and features in view the invention AWill noiv bedescribed in con'nectionvvitli thefaccompanying 'drawings' of an illustrative n'iachine,VVV and peinted out in the subjoined'ielaims.

f lfigp is a plan view-thereof;

Figs. l", 5 and 6 are horizontal sections on the vlines 4,5 and 6, respectively,`of'Fig. l.

fis illustrated the machineV is .provided with a supporting "frame l0 havinga deck 12, the latter having'an arcuate elevated por tion lli extending from one side to'the front of the machine and providing a surface on ivnich the'heel'sections maybe assembled. Supported above this arcuate surfacea're a pair of magazines 16, livhich inaybe of' anytype suitable to the storage and feeding of the heel sectionsor lifts. ils/"shown in Figs. 2 and 3 these magazines are a'djustably carried, as through scr'ev. and'slot connectionsV 19,' by a bracket 2O upstanding from thedeck of the machine. ln'the illustrated form each magazine is provided With a se.- ries of stripsl carried'by suitable frame lim n'ienibers 22 and which guide the heel sections in such a manner as to permit them to feed downward under the action of gravity. As illustrated these frame members 22 are adjustably connected as by screws 24 and springs 26, 28, to accommodate heel sections of different sizes. Each magazine is provided at its lower end with a gate pivoted at 32 to the deck of the machine and normally held beneath the magazine by a suitable torsion spring 84. These gates are provided each with a downturned portion 86 by means of which they may be opened to permit the downward feeding of the heel lifts, as will be hereinafter more fully described.

lt may be here noted that the herein disclosed magazine structure is shown primarily for purposes of illustration and that the invention is in no way limited thereto.

Suitably supported, as by a bearing 38 Carried by the deck of the machine is a shaft 40 mounted so as to be capable of both longitudinal and rotary movement. This shaft is rotatably connected as at 42 to a yoke 44, the latter being connected to a crank 46 driven from any suitable source of power in such a manner as to reciprocate rod 40. 'llo permit relative longitudinal movement of shaft 40 and the yoke 44 in case the machine jams, the shaft 40 may be connected to the yoke 44 through a spring 48, this spring being stiff enough to transmit to the rod 40 sufficient power to operate the machine under normal circumstances but being capable of yielding, nevertheless, in case of excessive strain.

Itigidly connected to the deck of the machine and surrounding the shaft 40 through part of its length is a sleeve 50 provided with a pair of slots each having a straight vertical portion 52 and a spiral portion 54. ,Surrounding sleeve 50 is a plunger illustrated as in the form of a sleeve 56 and connected with the shaft 40 by means of a pin 58 (see Fig. 6) rigidly connected both to the shaft 4G and to the sleeve 56 and having journaled thereon a pair of rolls 60 arranged to travel in the slots 52, 54 so that as the rod 4t) is elevated the plunger or sleeve 56 will 'first be elevated and then rotated. is the shaft 40 is lowered the reverse takes place. The sleeve 56 is provided with a pair of un-. dercut grooves 62 forming a way in which 4is mounted a bracket 64 having pivoted at its outer end, as shown at 66 in l* ig. l, the presser member 68. Sleeve 56 is provided with a bracket 6l adiustably connected by a screw 63 with a lug formed on bracket 64 so that the vertical position of the latter and of the parts which it carries may be appropriately adjusted.

The presser member 68 is designed to squeeze together heel sections or lifts which have been superimposed upon the support 14 and the contacting surfaces of which are coated with cement. A. comparatively light pressure will cause these cemented sections permanently to adhere to one another so that they may be transferred from the surface upon which they have been assembled and handled thereafter as units in the manufacture of shoes.

For the purpose of transferring the assembled heels from the assembling position and discharging them at a convenient place, the presser member 68 is provided with a brad or picker Y() and with a stripper' plate surrounding the picker and provided with a pair of springs 74 (Eig. l) tending to hold the stripper plate at such a distance from the body of the presser member that, as the presser member is lowered to squeeze the assembled heels, the springs i4 will be compressed so that the stripper member is squeezed into contact with the body of the presser member. rfhe picker "IO accordingiy penetrates the assembled heel and, since a latch is provided to hold the stripper plate in inactive condition as the presser member is lifted and rotated, the heel is lifted and transferred laterally. At the discharging position there is provided a chute 76 carrying an upstanding trip member 'T8 for the purpose of tripping the latch which holds the stripper plate in inactive condition so that the stripper plate operates to discharge the heel into the chute. As illustrated, this latch comprises a substantially L-shaped rod 80 (see Figs. l and 3) mounted in a sleeve 82 carried by the presser member, the head of the rod normally being held in engagement with a notch 84 formed in the stem 7l of the presser member. This may conveniently be accomplished by a compression spring 86 the arrangement being such that as the presser member moves to discharging position the extremity of rod 8O is thrust against the trip member 78 so that spring 86 is compressed, the head of the rod 80 moves out of the notch 84 and the stripper plate 72 is actuated by springs 74 to push the heel olf of the picker 70 so that it drops into the chute and is discharged thereby.

To transfer the heel sections from the magazine tothe surface l14 upon which they re to be superiinposed, the machine is provided with two automatically operated grippers 88, 90. These grippers are each pro` vided with a pair of pivoted faws 92 carried by a member 94 adjustably connected as by a bolt 96 and a dove-tail joint 97 with a block 98 journaled on the sleeve 50. Each block 98 is provided with a gear segment 100 rotated through suitable intermediate gearing by a gear segment 102 mounted upon a shaft 104 (Figs. l, 8 and 4). Sleeve 56 is provided near its lower extremity with a gear segment 105 arranged to engage, whatever' the vertical position of the sleeve 56, with an elongated gear segment 107 rigidly connectisc lll

ed toshaftilOt. Thus as the shaft l0 isrotated it moves the presser member 68 and the grippers 88, 90 in opposite directions sothat while the presser member isv transferring an assembledheel to therolischarge chute, the grippers are moving ,to their respective magazines to receive heel sections andwhile they are transferring these sections to the assembling position the presser member is returning' empty from the .discharge pointto a position over the support upon which the Lheel'lifts are to be superimposed. Since the distance from the different magazines to the assembling surface is different, the radii of the ditlerent gear elements are so arranged that the gripper which has the further to move will move the faster and that the .different grippers willileave their respective magazines simultaneously `and will arrive substantially simultaneously at the assembling position. In order, however', tojcompensate for any inaccuracy in the timing of the arrival of the grippers at theassembling position, each gear segment `102 is mountedloosely upon shaft 1 0-l and is conne ted thereto by a suitable clutch illustrated as a friction-slip device. Thusy in Fig. 1 the hubs 106 of gearslOQ, are held in frictional contact .with clutch members 108 carried by the shaft 104 by suitable springs 110, so that if either. of the "grippers reaches assembling position beforeits `gearing has quite completed its movementtheflappropriate clutch will slip Iand thegripper will remain statenary.

To .insure the `registration of different heel lifts at the assembling station, a preferably adjustable .stop112 is provided for each gripper beyond which the grippers cannot swing.

The two jaws- 88 of each gripperare provided with interengaginggear segments 114 to insure thesyinmetrical positioning of the jaws as they are moved towards andfrom one another. Springs 116 connect the jaws of each pair and tend tomove them together .with a force sufficient to griplaj heel and hold it during its traverse from the magazine to assembling position. The arm of each .gripper which isneXt to its magazine is provided with a tail 117 arranged to strike a preferably adjustable stop 118y (Fig. 3) to open the jaws of the gripper as the gripper moves into registration with the magazine so `that the jaws of the gripper will be spaced apart a distance somewhat greater than the width of the heel section which is to4 be received. As each gripper moves into registration with its magazine it strikes thedownturned portion 86 of the gate of the magazine and swings thegatelof the 'magazine out of registration with the heels in jthe magazine so V- that the lowermostv heel can drop down into the,spaceibetweenl-the jaws .Ot the. grppel- Beneath each magazine is a snpporting snrfacee1ther a portionof the deck ofthe machine or a plate l119 varra-,nged .at such a.
